“…Since the quality of braille printed on different substrate depends on the physical and mechanical characteristics of the substrate and used varnish which belongs to technological conditions and temperature and pressure of varnish, substrate feed rate as operating conditions, these components were studied in research done by Havenko et al in 2013. The samples were created with digital inkjet printer Braillemaker One Convertec using special transparent varnish Braille Maker Varnish 1.0 A. Different types of material can be printed using this machine.…”

Purpose This paper aims to highlight the importance of braille for visually impaired people and the possibility of printing it by using the ultra-violet (UV) inkjet printing technique. Design/methodology/approach The vision impairment, definitions and statistics, as well as braille letter and standards, are first reviewed. Then, the methods of printing braille have been discussed, with a focus on UV ink-jet printing. Finally, this study indicates a significant role of UV ink-jet printed Braille, its possibilities and its advantages. Findings Research studies in the field of UV ink-jet printed braille are showing that it is possible to print good legible braille of the adequate height of dots. This paper highlights some advantages of printing braille with UV ink-jet, like the possibility of achieving greater dot height than embossing and no need for printing form. Printing of additional elements on top of braille dot has also been tested, and possible use for differentiation of the written notation is shown. This paper also indicates the importance of technological and operating conditions in UV inkjet braille printing. It predicts a significant role of UV inkjet in braille printing. Originality/value This paper provides a detailed review of UV ink-jet printed braille: possibilities, advantages and application.

“…Research issues of ensuring blind people of printed tactile information devoted to works of local and foreign scientists, such as: Beskov, Vakulich, Havenko, Kibirkshtis, Labetska (Havenko, Labetska & Khadzhynova, 2013;Havenko et al, 2013a;Havenko, et al, 2013b;Havenko et al, 2015a;Havenko et al, 2015b;, Mayik (Mayik, 2013), Onishchenko, Stepien, and others, where considered problems of tyflo technology and equipment for the reproduction of information in Braille. However, analysis of the literature and patent information indicates the lack of deep scientific developments regarding to research of the tactile information durability, automation of control process of its quality.…”

The paper presents a model of factors that influence on the quality of relief-dot Braille inscriptions in their intensive use by blind people. It was constructed matrix of depending and distancing by using a directed graph. It allowed establish a hierarchy between studied criteria’s of impact the on durability of relief prints. It was developed a basic structure of digital system of assessment the conformity of Braille symbols to applicable international standards and definition of operational stability.

“…It is very important to provide blind and partially sighted people with an environment in which they will feel safe and have access to the necessary information. This can, among other things, be achieved by labelling products in Braille (Havenko et al, 2013). According to the European Directive 2004/27/EC (European Commission, 2005), labelling of pharmaceutical products has been mandatory since 2005, but it is expected that in the near future it will be mandatory to label a larger number of consumer products: food products, products for personal hygiene and care, products for space hygiene, etc.…”

“…The Braille formed on the labels is stronger and more stable compared to the embossed Braille, where the dots may collapse during transport, and also the problem may be to achieve the required dot height (Golob et al, 2013). (BOBST, 2021;ECMA, 2008) By analyzing scientific publications and patents Havenko et al (2013) provided a classification of available methods for Braille dot formation (Yim, 1996;Burman & Lofstedt, 2001;Labetska, 2012;Kibirkštis, Venytė & Lydekaitytė, 2012;Labetska & Havenko, 2012). They can be divided into two groups, namely contact and non-contact methods (Havenko et al, 2013).…”

They can be divided into two groups, namely contact and non-contact methods (Havenko et al, 2013). Contact methods include embossing on cardboard, special types of paper and films and screen printing (Figure 3a) on special papers with thick layers of non-flowing color or mixture, creating relief in the plane due to thermal imprint.…”

This paper investigates the possibility of reproducing Braille by UV ink-jet printing on self-adhesive labels, previously printed by flexo printing technology. The aim was to determine whether it is possible to reproduce Braille, the degree of quality of created Braille dots (cells), the legibility of Braille text, and how many layers of varnish are necessary for quality reproduction. The Braille letter was applied to the previously printed label (design) using 8, 10, 12, 14 and 16 layers of varnish. It has been found that it is possible to reproduce a quality and legible Braille. With the increase in the number of layers, the assessment of legibility and quality of reproduction by the respondents also increased. Samples reproduced with 12 layers of varnish received a very good grade of legibility and good grade for quality of Braille. Samples reproduced with 8 and 10 layers received bad grades for legibility, and even worse for quality, while samples with a higher number of layers of varnish, 14 and 16, received even better grades. The threshold for quality reproduction would therefore be the use of 12 layers of varnish, where a good ratio of workmanship and economy is obtained.
